Tag: How to grow cactus

Hi Guys 😀 In this Cactus care Blog I am talking about the very unusual and very wacky and yes a little bit naughty of a cactus called Myrtillocactus geometrizans var. ‘Fukurokuryuzinboku’ also known as ‘The Booby Cactus’

Myrtillocactus geometrizans Fukurokuryuzinboku is a monstrose cultivar of the more commonly seen Myrtillocactus geometrizans, but this Cactus has more unusual shaped ribs along with areoles that resemble nipples making this cactus appear like it has little breasts in appearance, this is why this cactus is often nicknamed as ‘The Booby Cactus’ or ‘Titty Cactus’.

Myrtillocactus geometrizans Fukurokuryuzinboku is a rare plant to find for sale and is only available from specialist cactus nurseries and online cactus nurseries but is now becoming more popular to grow in cultivation, it is definitely one of the more expensive cactus plants to buy.

It is a Japanese cultivar that can grow up to 4.5 metres high ( 178 inches ) and 10 cm wide in diameter ( 4 inches ).

LIGHT :

This cactus definitely like a nice sunny spot, however when these plants are still young ( less than 3 inches in height ) or if taken as cuttings they are best placed in a less sunnier position, however when cuttings have fully rooted and the plant is taller than 3 inches in height they love to be placed in a sunny position as long as ventilation can be provided. If grown on a very sunny south facing window in the middle of summer then a shade cloth may be placed over the window to allow indirect sunshine onto the plant this will prevent scorch or yellowing of the stem.

SOIL :

A very well draining cactus soil is an absolute must for these cacti as soil that stays wet for too long will encourage rot, a good quality well draining cactus and succulent soil mix is to be used and not any other type of houseplant soil. I like to make my own cactus soil up for these cacti and use a mix of 3 equal parts of Loam, Horticultural sharp sand, and Grit. Here is a video I have made for my You Tube Channel called Desert Plants of Avalon on How I make my own cactus soil and you can watch this video below:

WATERING :

From Spring until mid Fall / Autumn these cacti love to be watered very regularly always allowing the soil in their pots to fully dry out first before watering them again, this is a better guide I like to give to people because when it comes to watering all cacti, one size does not fit all haha, as it can depend on many different factors for example the temperature, the climate etc, but as a good rule of thumb during their active growing period of Spring until mid Fall I recommend to water every time the soil in their pots has fully dried out.

In Winter these cacti like to have a winter rest period and no water should be given from late Fall / Autumn until Spring. Its normal for these cacti to shrivel as they use up their water stores during winter and their little ‘breasts’ will start to shrivel haha ‘however if you are overwintering your cactus indoors in a heated room and notice that the cactus is looking a bit too shrivelled you can go ahead and water just enough to plump up the plant again, but avoid doing this if growing your cactus in a cooler environment e.g a greenhouse or polytunnel etc, due to the cooler temperatures and higher air humidity levels of a greenhouse or polytunnel or other outdoor structure, its better a few wrinkly ‘boobs’ than rotten ones haha, and your cactus will soon plump back up again in Spring when normal watering resumes.

Clean Rainwater is always best if you have access to it, but if not then let your tap water sit for 24 hours to help to dissipate some of the chemicals that are present in tap water.

FERTILISING :

From spring and Summer feed these cacti once every 3 weeks with a good quality cactus and succulent fertiliser. Do not feed at all in Winter when these plants are resting.

TEMPERATURE :

Myrtillocactus geometrizans Fukurokuryuzinboku can not take frost and in Winter this cactus must be kept above 10 Celsius / 50 Fahrenheit, many growers would recommend that they can take lower than this if kept totally dry over winter but personally I would not recommend it as Myrtillocactus has a tendency to scar and scab and at the worst case rot in low temperatures during the Winter months when they are dormant, especially in my climate in Ireland and the UK where the air humidity is very high outdoors in winter, if you live in a more arid winter environment and country then its possible these plants can take lower temps in Winter but avoid frost at all costs.

During the Spring and Summer these cacti can take very high temperatures as long as plenty of ventilation can be given. If growing behind glass, e.g in a sunny window or greenhouse or conservatory, sun room etc, then windows must be open or and a fan / doors etc for ventilation during very hot and sunny days.

Its best to re pot these cacti during their active growing period in Spring and Summer and only when the plant has outgrown its pot, as with all cacti its far better to under pot rather than over pot because too much soil around their roots can stay damp for too long and may encourage the chances of root rot.

FLOWERING :

Myrtillocactus geometrizans Fukurokuryuzinboku will bloom when mature from about 60 cm tall in height ( 24 inches ) The flowers form in Spring and are small white flowers.

PROPAGATION :

Propagation of Myrtillocactus geometrizans Fukurokuryuzinboku is from cuttings taken in Spring and Summer. Cuttings need to fully dry ( callus ) over for a couple of weeks or more until a hard white callus has formed at the base of the cut before planting up as cuttings. Cuttings of these cacti need very warm weather above 18 Celsius / 65 Fahrenheit to root for the best success, additional heat with a heat mat can help with rooting these cuttings if your Summers are cool and damp like mine in Ireland and UK.

Seed propagation of Myrtillocactus geometrizans Fukurokuryuzinbokus is not recommend, this is because this cactus is a monstrose variety of the original Myrtillocactus geometrizans and any seeds germinated will grow as normal Myrtillocactus geometrizans cactus plants and will not grow with the little ‘breasts’.

I hope you enjoyed reading and learning lots about this very bizarre and wacky cactus.

There are just three species of Aztekium, 1, Aztekium ritteri, 2, Aztekium hintonii, and 3, Aztekium valdezii.

Aztekium valdezii has only recently been discovered from 2011.

The Aztekium Cactus grows in its natural habitat in Mexico growing on steep cliff faces that consist of mostly gypsum and some limestone gravel.

Aztekium is extremely slow growing and forms into little clumps over many years, it is one of the slowest growing cacti both in natural habitat and in cultivation.

I have grown my Aztekium hintonii for over 23 years, I got it as a young seedling that was grown from seed from a Cactus Grower in the U.K called David Quail, it was the just size of my thumbnail and in all of that time it has grown only about 2 inches in height and width.

Because of their extremely slow growth and difficulty to grow when young on their own roots, these cacti are often seen for sale grafted onto other more hardier cactus stock, but once established on their on roots they can survive long term as long as a very careful watering is maintained and a very gritty well draining soil is used.

My 23 year old Aztekium hintonii

HOW TO CARE FOR:

LIGHT:

Aztekium like most cacti need bright light with some sunshine to grow healthy, however these cacti prefer to be protected from very strong midday sunshine and prefer more shade than a lot of the other types of Desert Cacti, and Aztekium would be best positioned where they can get either early morning or very late afternoon sunshine.

WATERING:

Aztekium prefer soft water that is not alkaline and clean rainwater is best to water these cacti with. Its best to avoid watering these cacti with water than has a pH higher than PH 7, as hard alkaline water can cause damage to the roots. If you use tap water check that the PH is not higher than PH 7 and allow the water to sit for 24 hours to allow the chlorine and other gases to dissipate.

If you are growing Aztekium that have been grafted, then the pH of the water is not as much a concern as most cactus stock used for grafting Aztekium are mostly Trichocereus or Pereskioposis, and these cacti are not so sensitive to water PH, however careful watering should still be given with all Aztekium cacti.

Water Aztekium from Spring through Summer ALWAYS allowing the soil in their pots to fully dry out before watering again.

Keep Aztekium totally dry throughout the Winter rest period with no water from Fall / Autumn and Winter, introduce water again from Spring when their active growing period returns.

SOIL:

The soil used for Aztekium must be extremely well draining, this is very important especially for Aztekium cacti that are growing on their own roots, especially when they are young as they can be very prone to rot, which is why they are often seen grafted. If grafted onto hardier root stock such as Pereskioposis and Trichocereus they are far less prone to rot and grow faster, but as with all cacti except the epiphytes, the more well draining the soil the better.

Some growers of Aztekium like to add lie to the soil, but I have had success over 23 years of growing this cactus with my well draining soil mix that I use for most of my arid loving cacti.

Avoid using peat and houseplant soils for these cacti as they need a VERY well draining and gritty soil.

I like to use a soil mix of 3 equal parts of loam, horticultural sand and grit for my Aztekium hintonii, For more information on How I make my own Cactus soil click HERE:

FEEDING:

Feed Aztekium once a month in Spring until mid Summer with a good quality cactus fertiliser. Because these cacti are extremely slow growing its best to use the fertiliser at half the strength they recommend for normal cacti.

FLOWERING:

The flowers on Aztekium are very tiny and white or pink or lilac coloured, they grow from the top of the cactus when the plant is mature often after many years.

Aztekium forms a woolly tuft and fine spines from the crown of the cactus when the plant is mature enough to flower.

I have not had my Aztekium flower for me in 23 years, but I hope one day to see flowers, patience is definitely the key when growing cacti haha, but I have heard of many growers who have had their Aztekiums flower after 10 years or less.

Grafted Aztekiums will flower much sooner than if grown on their own roots.

TEMPERATURE:

In Spring and Summer Aztekium can take high temperatures but they must be protected from extreme heat and strong midday sunshine, especially if they are grown behind glass in glasshouses or windowsills, and they like to have plenty of ventilation.

In Winter its best to overwinter Aztekium cool and dry above 5 Celsius / 41 Fahrenheit

PROPAGATION:

Propagation of Aztekium is done by seed that are very dust like, but it is extremely difficult and slow to grow from seeds, although germination rate can be high at first lots of seedlings will often die within the first few months of germination.

I have never tried to grow these from seed myself but when my Aztekium flowers for e in the future and I get seed I will definitely have a go at trying to grow this amazing and unique little cactus from seed.

In this Blog I will be talking about a rather unusual and very unique little Cactus called Puna clavarioides also called The Dead man’s fingers Cactus, Mushroom Opuntia, Maihueniopsis clavarioides, Opuntia clavarioides, Opuntia ruiz-lealii, Opuntia Puna clavarioides.

This weird and wacky Cactus is the type species of the genus Puna also known as the genus Maihueniopsis.

The Puna genus of cacti are some of the most diverse cacti of the opuntiads and are closely connected to Opuntia, Tephrocactus and Austrocylindropuntia.

These Cacti are all part of the very large group of the Opuntioideae Family of Cacti. The Opuntioideae Family of Cacti are commonly known as ‘The Prickly Pear’

Puna clavariodes is a low growing geophyte cactus that grows in clusters up to 15 cms tall, with conical shaped stems of reddish brown to dark green to grey colour that emerge from tuberous roots.

In natural habitat this Cactus is found in Argentina growing in high altitude on rocks and sand between 2,000 -3,000 metres above sea level in a very dry arid environment.

The Puna clavariodes Cactus although part of the Opuntioideae Family of Cacti does not have glochids that are more commonly associated with the Opuntioideae.

The flowers on this cactus are a yellow /green colour and about 4 cms in length.

This Cactus is rare in cultivation and therefore not commonly seen for sale and when it is for sale it is more commonly sold as a cristate form that is often grafted onto a grafting stock cactus such as Trichocereus spachianus.

CARE & CULTIVATION:

LIGHT:

Puna clavariodes likes a bright and sunny position all through the year, but can tolerate some light shade too but these Cacti grow better in full sun as long as they are protected from very strong heat.

A bright sunny greenhouse or a south facing window is ideal if protected from heat and sun scorch from glass on very hot Summer days.

WATERING:

Water well in Spring and Summer but ALWAYS allow the soil in the pot to fully dry out before watering again as these Cacti are very prone to rot if kept too wet due to their tuberous root systems.

Clean rainwater is always preferred if it is available, but tap water is ok as long as the Ph of your water is not too high ( above 7,5 pH ) Its always best to let tap water sit for 24 hours before using it to allow some of the chemicals to dissipate.

Keep this Cactus totally dry over the Winter dormancy period with no water given whatsoever.

SOIL:

Puna clavariodes likes a very well draining mineral soil as this cactus is very prone to rot due to the tuberous root system and a well draining soil is a must. I like to use a soil mix of 3 equal parts of a Loam based soil with with Horticultural sand and grit. Check out my page on this website on GROWING MEDIUMS for more advice on How to Make Your Own Cactus Soil.

RE POTTING:

Re pot only in Spring and Summer when this cactus is actively growing, this is because it is a slow growing cactus and because of the tuberous root its best to keep this plant in a clay pot that is deep enough just to cover the tuberous root, it is always safer to under rather than over pot.

Do not water this cactus for the first 2 weeks after re potting to allow the roots and tuber to acclimatise.

FERTILISING:

Feed Puna clavariodes in Spring and Summer every month with a Cactus fertiliser diluted at half strength, this is because this cactus is a slow growing plant and does not require lots of fertilising.

FLOWERING:

Puna clavariodes flowers in Spring and Summer with yellow blooms. A dry winter rest period will help to encourage blooming the following year.

TEMPERATURE:

Puna clavariodes likes to be kept above 5 Celsius / 41 Fahrenheit in the Winter months, but can take lower temperatures than this if growing this cactus in a very dry arid climate.
